It has an apparent magnitude of about 9.5, and an apparent diameter of 7 arc minutes, and class VIII with stars of magnitude 15 and dimmer. It is about 2 degrees south east of Gamma² Sagittarii. The globular cluster was discovered in 1784 by the astronomer William Herschel with his 18.7-inch telescope and was catalogued later in the New General Catalogue.{{cite web|url=http://cseligman.com/text/atlas/ngc65a.htm#6569|title=New General Catalog Objects: NGC 6550 - 6599|author=Courtney Seligman|access-date=13 February 2017}}
